There is plenty to worry about with a kindergartener.
They are tiny balls of cosmic energy focused entirely on whatever whim enters their head at any given moment and prone to forgetting anything they learned at school that week in favor of committing a particularly quirky and fun limerick to memory and shouting it, loudly, inside the house and to passerby at the park.
They are perfect and flawed, just like all of us, only more so and without the inhibitions and anxieties brought on by knowing exactly what the world is and what is lurking in it.
It seems great, to be honest.
